>>55229344>>55229534Probably not strong enough to be its own deck, but at least baby moon is a better single prize attacker than yveltal or morpeko. 190hp with a booster and a sada target is a decent lead.
Your late game discard pile for a roaring moon ex deck would probably be:
>4 sada>4 vessel>2 booster capsule>2 roaring moon exGiving you around 12 in the discard or 190 damage. Definitely not main attacker material unless some kind of ancient box deck manages to cram in a bunch of pokemon and discard synergy.
